Specification of Letters Patent.

Patented Jan. 106, 191W..

To all whom t may concern:

Be it known that I, ERNEST E. ASPIN- WALL, a citizen of the United States, residat Pawtucket, in the county of Provr Machines for Glazing andv Finishing Yarns,-

Threads, and Twines, of which the following is a specification.

This invention relates to certain new and useful improvements in machines for glazing and finishing yarns, threads and twines, and it purposes to provide a machine which will operate eiiiciently in applying size or finish to yarn,drying and glazing or otherwise finishing the surface of the yarn subsequent to the application of the size.

The invention further resides in forming the lower size or squeeze rolls hollow andV heating the same to stantly warm.

Another object of" the invention is to prokeep the sizing convide a brush roll rotating reversely to the` traverse of the yarn for acting upon the latter.

Other aims will be hereinafter set forth and claimed, the preferred embodiment of the invention being depicted in the drawings wherein- Figures 1 yand la show themachine from one side and in elevation. Figs. 2 and 2a depict the machine in elevation from the opposite side thereof.

Referring now to Figs. 1, l?, 2, and 2a, the immersion rollsv 4 and 16 are pivotally connected, respectively to vertically movabley rack members 30 and 30. ter being joined at their top portions by. a rod 32, the rack members 30 and 30 being slidably disposed in brackets 33 in which are journaled drive pinions 34. These pinions mesh with the rack portion of members 30 and 30 and are The immersionA rolls slidey in the respective guides 5-17and are to direct and immerse the yarn inthe size or, iinish while the machine is in operation. When the machine is idle, these rolls are elevatedfrom the box so that the yarn will not absorb or collect an excess of the size or finish and render it harsh or stili'. By inclining the guides the immersion rolls are lowered in proximity to and beneath the size rolls where they combinedly agitate the size or finish. rllhe disposition of these guides permits of the immersion rolls being held against vibratory by links 31, the latrotatable by cranks 35. 'f

or swinging movements and, further, provides Sufficient rack members to enable the operative to work about the machine with facility.

The lower size or squeeze rolls 7 andy 19 are hollowl for the circulation of steam therethrough. Steam is admitted axially through pipe 36 on one side o the machine and escapes from the opposite side throughl pipe 37. Between a pipe 36 and its size roll is a sprocket 38, while a suitable stuffing box 39 1s employed to eliminate leakage of the size from the size box.

The size rolls are arranged within the size boxes to remove by pressure or to squeeze from the yarns all surplus size or finish, the top rolls 8 and. 20 being covered l with a cloth to form a soft cushion to aidl in the squeezing. Normally, the top size roll is heavy enough to remove all surplusage when a light iinish is used. However, for a heavy iinish additional pressure is obtained by a pair of weighted levers 40 pivoted to the main frame 41, as at 42. The main frame is provided with seats 8 and 20 in which the top Size rolls are engaged when inoperative so as to keep the rolls away from the yarns which will hang in suspense and remain free from contact with wet size rolls. The size and linish in the boxes 6 and 18 are kept above a certain temperature in order to keep the material in liquid form so that the same will penetrate into and causeit to adhere more firmly to the yarn. The heat necessary for maintaining the size and finish in liquid form is supplied by means of steam and hot water. Furthermore, this supplied heat is necessary ito assist the evaporation of the moisture in the size and iinish since moisture is more easily evaporated when warm than cold.

rlhe wipers which are arranged to the rear the size rolls remove any and all surplus size and iinish as well as lay the fiber onto the yarns during movement of the latter and by means of pressure. Y Each an adjustable element 10-22, said elements having angular end flanges or extensions bolted to the upper bars of the frame, the adjustable element being slidably mounted on the main frame through pin and slot connections 43, as depicted in Fig. 1. The opposing surfaces of the wiper elements are soft and brought together so as to encompass space between they rolls and.,

wiper com-- prises a fixed strip-like element 9-421, and

the yarn to cause the fibers to be drawn back and embedded into the size and nish. The wiper elements are separable for passing the yarns therebetween.

Subsequent to passing between or through the wipers, the yarn is separated by the scored rolls 12 and 23 which are journaled in brackets or arms 44 adjustably mounted on arched supports 45. These supports are arranged on the main frame at the ends of the rotary brushes and each comprises a flat, strip-like, arcuate body having radial foot portions extending in opposite directions from its ends for being secured to the upper horizontal bars of frame 41. This arrangement enables the journaling of the brushes on the frame bars concentric with the arched supports 45. The rolls 13-25-14 and 26 are likewise adjustably supported from the arched supports by the brackets 46 and 47 which are adjustable circumferentially of the brushes in spaced arcuate slots formed in each of said supports. By adjusting these rolls at greater or lesser angles, more or less contact with the brushes is afforded.

The circular brushes 11-24 which are designed to polish the yarns, are revolved in opposite direction to the traverse of the latter. The main frame is provided with panels (not shown) for forming an inclosure or chamber in which are located the steam. pipes 48, the latter supplying heat to warm the brushes to thereby further effect evaporation of moisture in the size or nish on the yarn.

Steam pipes 36 and 48 are suitably connected to a source not here shown.

The tension rolls 27 are disposed in vertical slots 50 of standards 51 and are driven to draw the yarns from and into the brush so as to create a tension and friction on the latter such as is necessaryI to polish or glaze A the finish and thus eliminate back lashing on the brush which revolves in the opposite direction. These rolls are covered with a soft cushion to afford a better grip and avoid friction and chang therebetween.

In instances where two sets of size rolls are employed such as is illustrated, the second set of rolls 19-20 are driven to serve the purpose of tension rolls.

The brushes are driven from a source of power by the belt P and pulley Il mounted on the shaft of the brush frame 1l', a sprocket being secured to the opposite end of said shaft over which passes the chain 54 to the sprocket 55', causing rotation of the brush frame 24 and the sprocket 58 causing rotation of the sprocket 53 by means of the chain 53. The shaft of the sprocket 53 passes across the end of the machine and carries at one side the pulley 52 which causes rotation of the pulley 52 by reason of the connecting belt, the pulley 52 in turn causing rotation of the rolls 27 by reason of the belt 56, pulley 56 and pulley 56". On the opposite end of the shaft of the sprocket is secured the gear 59 which is in mesh with the gear 60 which drives the chain 57, causing rotation of the sprockets 38-88 and the squeeze rolls 7-19. Suitable tension is applied to the chain 57 by the roll 61.

In some instances speed changing gearing (not shown) will be employed for obvious reasons.

Throughout the specification and claims, the word yarns is used to signify also threads and twines.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- In a machine of the character described, a frame having spaced upper bars, arcuate strip-like supports having inwardly and outwardly extending radial foot-portions on their ends secured to the frame bars, each support being provided with a series of circumferentially spaced arc-shaped slots, independently adjustable brackets secured in the support slots-in radial disposition, rollers supported by the brackets, and a brush iourn aled on the frame bars between the foot portions of the arcuate supports and in concentric relation with the latter.

In testimony whereof I have signed my' name to this specification in the presence of two subscribing witnesses.

ERNEST E. ASPINWALL.
